摘　　要：以碳四溶剂脱沥青装置生产的脱油沥青为硬组分,选择切割不同馏分的组分作为软组分,采用调合工艺生产出GB/T 15180中低标号沥青AH-30;但由于延度不合格,用催化油浆不能调合出低标号沥青AH-50。Through blending process, the AH -30 low grade asphalt could be produced by using deoiled asphalt produced from C4 solvent deasphalting unit as hard component and selecting catalytic slurry oil of different component as soft component . But the AH -50 low grade asphalt could not be blended from catalytic slurry oil due to the ductility problem.
